Abstract
Ag nanoparticles functionalized flower-like molybdenum disulfide (MoS2) hybrid nanostructures (AgNPs/MoS2) were successfully synthesized by a facile hydrothermal method. The structure and surface morphology were subsequently characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) techniques. The as-synthesized AgNPs/MoS2 hybrid nanostructures were modified on a glassy carbon electrode (GCE) and further utilized for amperometric hydrogen peroxide (H2O2) detection. The electrochemical behaviors and sensing performance of the AgNPs/MoS2/GCE were studied by cyclic voltammetry (CV) and single-potential amperometry methods. The obtained results have demonstrated that the developed AgNPs/MoS2/GCE amperometric sensor possesses an excellent catalytic performance toward the reduction of H2O2. The as-prepared electrochemical sensor exhibits fast response time of less than 3 s, large linear detection range of 0.025-135.2 mM (R-2=0.998) and high sensitivity of 54.5 mu A.mM(-1). cm(-2). Moreover, the developed H2O2 sensor has shown good anti interference ability, outstanding stability and reproducibility, which represents a great potential for H2O2 detection in practical applications.
